The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0045] like Figure 1-11 As shown, a preferred storage device according to an embodiment of the present invention includes a rotating shaft 1, a connecting member 2 and a driving mechanism 3.

[0046] The rotating shaft 1 has a first axis 10, and the rotating shaft 1 includes a shaft body 11 and a first abutting portion 12. The first abutting portion 12 is fixedly connected to the outer wall of the shaft body 11, and the first abutting portion 12 has a first abutting wall 121 and a second abutting wall 122; the connecting member 2 is fixedly connected to the shaft body 11; the driving mechanism 3 includes a driving member 31, the driving member 31 has a through hole 311, the shaft body 11 is penetrated by the through hole 311, the driving member 31 has a first driving hole 312 connected to the through hole 311, the first driving hole 312 has a first driving wall 3121 and a second driving wall 3122, the first abutting portion 12 is penetrated by the first driving hole 312, the first driving wall 3121 is opposite to the first abutting wall 121, and the second driving wall 3122 is opposite to the second abutting wall 122.

[0047] Among them, the driving member 31 has a first state, a second state and a third state; when the driving member 31 is in the first state, the first driving wall 3121 abuts against the first abutting wall 121 and can drive the rotating shaft 1 to rotate around the first axis 10 along the first direction S, and there is a gap between the second driving wall 3122 and the second abutting wall 122; when the driving member 31 is in the second state, the first driving wall 3121 and the first abutting wall 121 have a gap, and there is a gap between the second driving wall 3122 and the second abutting wall 122; when the driving member 31 is in the third state, the second driving wall 3122 abuts against the second abutting wall 122 and can drive the rotating shaft 1 to rotate around the first axis 10 along the second direction N, there is a gap between the first driving wall 3121 and the first abutting wall 121, and the first direction S and the second direction N are opposite.

[0048] Based on this technical solution, when the driving member 31 is in the first state, the driving member 31 remains stationary, and by inputting power at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate along the first direction S around the first axis 10, the first abutting wall 121 will disengage from the first driving wall 3121 and switch the driving member 31 from the first state to the second state; the rotating shaft 1 continues to rotate along the first direction S around the first axis 10, which will increase the interval between the first abutting wall 121 and the first driving wall 3121 and reduce the interval between the second abutting wall 122 and the second driving wall 3122; before the second abutting wall 122 abuts against the second driving wall 3122 (i.e., the driving member 31 has not switched from the second state to the third state Because there is a gap between the second abutment wall 122 and the second driving wall 3122, the rotation of the rotating shaft 1 around the first axis 10 in the first direction S will not drag the driving member 31 in the opposite direction, and the driving member 31 will not generate resistance to the rotation of the rotating shaft 1, so that it is easy to input power at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to adjust the angle of the seat back along the first direction S around the first axis 10, thereby improving the flexibility of adjusting the angle of the seat back; similarly, when the driving member 31 is in the third state, the driving member 31 remains stationary, and the second direction N can be increased by inputting power at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate around the first axis 10 in the second direction N. The spacing between the abutting wall 122 and the second driving wall 3122 reduces the spacing between the first abutting wall 121 and the first driving wall 3121; before the first abutting wall 121 abuts against the first driving wall 3121 (that is, before the driving member 31 switches from the second state to the first state), due to the spacing between the first abutting wall 121 and the first driving wall 3121, the rotation of the rotating shaft 1 around the first axis 10 in the second direction N will not drag the driving member 31 in the opposite direction, and the driving member 31 will not generate resistance to the rotation of the rotating shaft 1, so that it is easy to input power at the end where the connecting member 2 is located (that is, the end where the backrest is located) to adjust the angle of the seat back around the first axis 10 in the second direction N, thereby improving the seat Flexibility in adjusting the angle of the backrest; In summary, the storage device provided by the present invention, by arranging a first abutment portion 12 on the rotating shaft 1 and arranging a first driving hole 312 on the driving member 31, can place the driving member 31 in the first state or the third state so that the driving wall of the first driving hole 312 abuts against the abutment wall of the first abutment portion 12, so as to realize the flipping and storage function of the backrest through the storage device, and can also place the driving member 31 in the second state so that the driving wall of the first driving hole 312 and the abutment wall of the first abutment portion 12 have a gap, so that when the angle adjustment function of the backrest is realized through the storage device, the rotating shaft can be prevented from dragging the driving member in the opposite direction, thereby improving the flexibility in adjusting the angle of the backrest and facilitating use.

[0049] When the driving member 31 is in the first state, the rotating shaft 1 remains fixed, the driving member 31 rotates around the first axis 10 along the second direction N, the first driving wall 3121 will disengage from the first abutting wall 121 and the driving member 31 will switch from the first state to the second state; the driving member 31 continues to rotate around the first axis 10 along the second direction N, which will increase the interval between the first driving wall 3121 and the first abutting wall 121 and reduce the interval between the second driving wall 3122 and the second abutting wall 122, until the second driving wall 3122 abuts against the second abutting wall 122, and the driving member 31 switches from the second state to the third state; similarly, when the driving member 31 is in the third state, the rotating shaft 1 remains fixed, the driving member 31 rotates around the first axis 10 along the first direction S, and the driving member 31 can be switched from the first state to the second state and from the second state to the third state.

[0050] In this embodiment, the first abutting portion 12 is integrally formed on the outer wall of the shaft body 11 .

[0051] In this embodiment, the first axis 10 is the central axis of the rotating shaft 1 .

[0052] In this embodiment, the first direction S is a clockwise direction, and the second direction N is a counterclockwise direction.

[0053] In some other implementations, the first direction S may be counterclockwise and the second direction N may be clockwise, which is not limited here.

[0067] Preferably, the first connecting wall 123 is a first arc-shaped connecting wall, and the second connecting wall 3123 is a second arc-shaped connecting wall, and the first arc-shaped connecting wall and the second arc-shaped connecting wall are in contact with each other. The configuration in which the first arc-shaped connecting wall and the second arc-shaped connecting wall are in contact with each other can not only enable the first abutting portion 12 and the driving member 31 to be quickly assembled and positioned when the rotating shaft 1 and the driving member 31 are assembled, thereby reducing the difficulty of assembling the rotating shaft 1 and the driving member 31; and can also guide and limit the first arc-shaped connecting wall during the relative rotation of the driving member 31 and the rotating shaft 1 (i.e., during the switching of the driving member 31 between the first state, the second state, and the third state), thereby ensuring the precise position of the first abutting portion 12 in the first driving hole 312 and improving the motion consistency between the driving member 31 and the rotating shaft 1.

[0068] The first abutting portion 12 further includes a first arcuate transition wall 124 and a second arcuate transition wall 125. The first abutting wall 121 is connected to one end of the first connecting wall 123 via the first arcuate transition wall 124, and the second abutting wall 122 is connected to the other end of the first connecting wall 123 via the second arcuate transition wall 125. The first arcuate transition wall 124 and the second arcuate transition wall 125 can reduce stress concentration at the connection position between the abutting wall and the first connecting wall 123, thereby improving the durability of the first abutting portion 12, and can also avoid the formation of sharp features at the connection position between the abutting wall and the first connecting arm, thereby preventing the first abutting portion 12 from scratching the hole wall of the first driving hole 312;

[0069] The first driving hole 312 also has a third arcuate transition wall 3124 and a fourth arcuate transition wall. The first driving wall 3121 is connected to one end of the second connecting wall 3123 via the third arcuate transition wall 3124, and the second driving wall 3122 is connected to the other end of the second connecting wall 3123 via the fourth arcuate transition wall 3125. The third arcuate transition wall 3124 and the fourth arcuate transition wall 3125 can reduce stress concentration at the connection position between the driving wall and the first connecting wall 123, thereby improving the durability of the driving member 31.

[0070] The rotating shaft 1 also includes a second abutting portion 13, which is fixedly connected to the outer wall of the shaft body 11 and is symmetrically arranged with the first abutting portion 12. The driving member 31 has a second driving hole 313, which is connected to the through hole 311 and is symmetrically arranged with the first driving hole 312. The second abutting portion 13 is passed through the second driving hole 313. In this way, when the driving wall of the first driving hole 312 abuts against the abutting wall of the first abutting portion 12, the driving wall of the second driving hole 313 will also abut against the abutting wall of the second abutting wall 122, so that the driving member 31 can evenly and balancedly transmit the torque to the rotating shaft 1 and drive the rotating shaft 1 to rotate, avoiding vibration and wear caused by imbalance when the rotating shaft 1 rotates, thereby enhancing the stability and reliability of the connection between the driving member 31 and the rotating shaft 1.

[0071] In this embodiment, the second abutting portion 13 is integrally formed on the outer wall of the shaft body 11 .

[0072] See also Figure 9-Figure 14 The driving member 31 has a preset position in the second state. The driving member 31 rotates from the preset position around the first axis 10 along the first direction S by a first preset angle a, and the first driving wall 3121 can abut against the first abutting wall 121, so as to switch the driving member 31 from the second state to the first state. The driving member 31 rotates from the preset position around the first axis 10 along the second direction N by a second preset angle b, and the second driving wall 3122 can abut against the second abutting wall 122, so as to switch the driving member 31 from the second state to the third state.

[0073] The maximum idle travel angle c=a+b of the rotating shaft 1 around the first axis 10 without reverse dragging the driving member 31. Exemplarily, when the driving member 31 is in the first state, the driving member 31 is kept stationary, and power is input at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate around the first axis 10 in the first direction S by the maximum idle travel angle c, which will not cause the rotating shaft 1 to reverse drag the driving member 31; when the driving member 31 is in the preset position of the second state, the driving member 31 is kept stationary, and power is input at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate around the first axis 10 in the first direction S by the first predetermined angle a, It will not cause the rotating shaft 1 to drag the driving member 31 in the reverse direction. Inputting power at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate around the first axis 10 along the second direction N by the second predetermined angle b will not cause the rotating shaft 1 to drag the driving member 31 in the reverse direction. When the driving member 31 is in the third state, the driving member 31 is kept fixed. Inputting power at the end where the connecting member 2 is located (i.e., the end where the backrest is located) to drive the rotating shaft 1 to rotate around the first axis 10 along the second direction N by the maximum idle travel angle c will not cause the rotating shaft 1 to drag the driving member 31 in the reverse direction.

[0074] Preferably, 5°≤a≤30°.

[0075] In this embodiment, a=15°.

[0076] In some other embodiments, the first predetermined angle a may be any angle value such as 5°, 8°, 10°, 20°, 25°, 30°, etc.

[0077] Preferably, 5°≤b≤30°.

[0078] In this embodiment, b=15°, that is, c=30°.

[0079] In some other embodiments, the second predetermined angle b may be any angle value such as 5°, 8°, 10°, 20°, 25°, 30°, etc.

[0080] The present invention also provides a seat, comprising any one of the above-mentioned storage devices.

[0081] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
